PROTECTIVE BOOK COVER.

Application filed April 22, 1922. flerial No. 556,038.

To all whom it may concern:

Be it known that I, Oscar V. Lawson, a citizen of Canada, and a resident of the city of New York, Corona, borough of Queens, in the county of Queens and State of New York, have invented a new and Improved Protective Book Cover, of which the following is a full, clear, and exact description.

This invention relates to protective book covers designed to present a pleasing appearance as well as a structure for protecting the backs of books.

The object of the invention is to provide a protective book cover which may be readily applied and also readily removed whenever desired.

Another object of the invention is to provide a protective book cover which may be readily folded to the proper size and secured together in a proper shape and then applied.

A still further object of the invention is to provide a protective book cover which may not only be folded to the proper size but which may be reversed at any time whereby both sides of the cover may be exposed to view but at different times and thus the full benefit of the cover secured.

In the accompanying drawings- Figure 1 is a perspective View of a book with the protective cover embodying the invention applied thereto.

Figure 2 is a perspective view of the protectivc cover folded and ready to be applied either with the reverse or obverse sides facing outward. I

igure 3 is a plan view of the cover before it is folded into tubular form.

Figure 4 is a plan view of the protective cover lookin at the same from the opposite side to that s own in Figure 3 and with one edge folded over part of the back of a book.

Referring to the accompanying drawings by numeral, 1 indicates a book of any desired kind provided with the usual back and covers 2 and 3, said covers, back and book forming no part of the present invention. As is customary for school children and other persons, covering devices of various kinds have heretofore been provided for covering the back and covers 2 and 3. Most of these devices were merely covering members folded to the desired shape and secured in place by adhesive or some other means. Also, corner members and other forms of covering have been provided but nothing which is designediy formed to be accurately folded along indicating lines and then used with either side facing outwardly.

in the present invention, means have been provided along this line and one embodiment of the invention is shown in the accompanying drawings. As indicated in Figure 3., the protective cover is formed from a single blank 4 which is rectangular and provided with an edging 5 of adhesive material and columns 6 and 7 of indicating lines preferably with numbers opposite each line, the numbers in column 6 correspondin exactly with the numbers in column 7.

on it is desired to fold the cover to fit book 1, the book may be arranged as shown in Figure 4 with one of its covers 2 opened wide. The cover 2 is spaced substantially centrally on one edge of the blank shown in Figure 3 and then the edge 8 turned over for forming a flap 9 as shown in Figure 4 whereby the numbers in columns 6 and 7 will appear uppermost and in position for ready reading. The edge having the adhesive 5 is then turned over thus forming an overlapping flap 10. When the edge havin the adhesive 5 is folded over it is move' until the fold fits against the edges of the book cover 2 and when this has taken place the edge having the adhesive will be on the line marked 5 in column 6 as well as on the line marked 5 in column 7. The cover is then removed from the book cover 2 and the adhesive 5 moistened, after which, the flap 10 is turned over until the edge is in line with the two lines 5 in columns 6 and 7. The fiap is then pressed downwardly so that the adhesive will perform its function of securing the two parts toether.

This will form an enclosure or flattened tubular structure with both ends open. One end of the tube is then fitted over the book cover 3 and the remaining part folded around the back of the book so that the opposite end may be fitted over the book cover 2 after said book cover has been turned to a wide open position.

It will thus be seen, that the opposite ends of the cover are fitted or so to speak telescope over the opposite book covers 52 and 3 and that its width as indicated in Figures 2 and 4,'will be slightly more than the height of the book. Ordinarily, the protective cover is left in the position just detakes the place of two ordinary covers which connot be reversed.

In case the book is larger than shown in Figure 4, the edge carrying the adhesive 5 will naturally reach one of the lower numhere, as for instance, number 3 in columns 6 and 7 and if the book should be smaller, the edge having the adhesive 5 will reach one of the higher numbers, as for instance,

number 11 in column 6 and 7. In this way a single cover is readily adaptetd for books of different sizes within certain limits.

It will be noted that by my eculiar construction I secure a series 0 advantages never before realized in protective book covers of the class in question, among them the following:

The structure being a continuous tubular one with entirely unattached ends it is possible to fold both ends so that they shall lap upon opposite sides of the central tubular body part thus enabling the reversal of the cover and the presentation of difierentsides outwardly and this possibility not only prolongs the life of the cover and maintains its cleanly appearance, but also enables the name of the book or other printed matter usually produced on such covers to be presented outwardly whether the cover be reversed or in its primary position. The printing, of course, being properly loarness the material from which the cover is made are always availed of for the protection of the book.

What I claim is l. A protective book cover which is tubular throughout and both ends of which are free to be folded in either direction toward the central part, the end tubular portions fitting over the book covers when folded in either direction.

2. A book cover blank, comprising a rectangular sheet having a pair of similar columns of gradations terminating adjacent opposite edges thereof, and an adhesive material near an edge at right an les to the gradations and on the opposite Face of the sheet.

3. A protective book cover, comprising a rectangular sheet folded upon itself to form a tubular body substantially longer than its Width, adhesive material carried by one edge of the sheet and acting to secure said edge to a part of the sheet near the opposite ed e to hold the same in its tubular form, the ends of said tubular body being adapted to be folded in either direction over the back of a book with the ends thereof telesooped over the book covers, whereby the book cover may beheld in place, but is easily removable by a sliding action.

4:. A tubular book cover having both ends thereof open and adapted to be folded in either direction toward the central part and to be telescoped over the covers of a book so as to constitute a protective cover having a plurality-of thicknesses on the outside of the book covers.
